Accompanying drawing 2 is the another kind of structural representation of the present invention.
Detailed description of the invention
By the examples below, and in conjunction with accompanying drawing, technical scheme is described in further detail.
Embodiment 1: the present invention eliminates the noise magnetic vibration absorber, and as shown in Figure 1, it includes plate pad 3, plate pad 3 is provided with set 6, and set 6 is the cavity body of one end closing, and opening is resisted against plate pad 3 and tips upside down on plate pad 3, sets pedestal 9 and silica gel ring 7 in the cavity of blind end; Pedestal 9 periphery is hierarchic structure, and its miner diameter end end passes from the blind end of set 6; Silica gel ring 7 is sheathed on the miner diameter end of pedestal 9, and both sides bear against the medial wall of the sidewall at pedestal 9 bigger diameter end and set 6 blind ends; Arranging hole, location on pedestal 9 bigger diameter end end face, location arranges silicagel pad 8 in hole, and the base portion of upper silicagel pad 8 is placed at the bottom of hole, hole, location; Upper silicagel pad 8 is arranged below lower silicagel pad 4, and the base portion horizontal of lower silicagel pad 4 is on plate pad 3; The base portion of upper silicagel pad 8 and lower silicagel pad 4 is provided with cylinder, and the end of two cylinders is oppositely arranged and distinguishes the two ends of sheathed spring 5. This structure, under external force, pedestal is under the guiding of silica gel ring, and the cavity inner wall along set declines, simultaneously extrusion spring, and spring transmits the force to lower silicagel pad, and lower silicagel pad passes to backing plate again; In power transmittance process, spring, upper silicagel pad, lower silicagel pad play good damping effect.
Silica gel ring 7 is column structure, and outer peripheral face is resisted against the cavity medial wall of set 6. The height of cylinder, the i.e. width of outer peripheral face, add the contact area of silica gel ring 7 and set 6, add the length that effectively leads that silica gel ring provides for pedestal slip, make pedestal slide more steady, also strengthen support degree simultaneously, directly can contact between pedestal with set, vibration is avoided to pass to set 6 from pedestal 9, thus obtaining better effectiveness in vibration suppression.
At the pedestal 9 end one section of damping trough 11 provided circumferentially about stretching out set 6, damping trough 11 circumferentially face encompasses annular; When being in off working state, damping trough 11 width is more than the distance between upper silicagel pad 8 cylinder and lower silicagel pad 4 cylinder, and the lower lip of damping trough 11 is in the outside of set 6 blind end outer faces.
Upper silicagel pad 8, lower silicagel pad 4 and cylinder thereon are hollow structure. Hollow structure increases elasticity, when the cylinder of upper silicagel pad, lower silicagel pad leans, increases the deformation space of cylinder, improves the elasticity of cylinder, strengthens effectiveness in vibration suppression.
The bottom of hollow structure arranges pin 1 and constitutes fixed structure, and pin 1 is in silicagel pad 8, the length of lower silicagel pad 4 is not more than the length of place cylinder half. Pin 1 can be fixed on electroplax and pedestal 9 by screw.
Plate pad 3 is slab construction, and lower surface is equipped with silica gel pad 2. During use, when backing plate 3 is connected such as threaded with external stability plane, silica gel pad 2 plays damping effect between backing plate and fixed pan, improves overall effectiveness in vibration suppression further.
Plate pad 3, set 6, pedestal 9 are non-magnetic material, for instance aluminium alloy; Silica gel pad 2, lower silicagel pad 4, silica gel ring 7, upper silicagel pad 8, silica gel lid 10 are non-magnetic material, for instance adopt silica gel to make. Plate pad, set, pedestal are aluminum alloy material, constitute the enclosed construction with demagnetizing action.
It is provided with silica gel lid 10 in pedestal 9 end stretching out set 6; Arranging annular groove on the periphery of pedestal 9 end, annular groove is inclined-plane close to the sidewall of the side of end face, makes annular groove A/F more than slot bottom width; Silica gel lid 10 main body is plate body, and periphery extends into annular wall to bottom reversed, and the upset to the inside again of annular wall opening extends to form crozier, and crozier medial wall is the inclined-plane adaptive with the annular groove on pedestal; Crozier buckles in annular groove.
Embodiment 2: as shown in Figure 2, upper silicagel pad 8, lower silicagel pad 4 cylinder be provided with cylinder 12; Cylinder 12 hole portion is placed on the cylinder periphery of correspondence, the turned-out flanging that changes into of root, and flanging is resisted against silicagel pad 8 or the base portion of lower silicagel pad 4; Cylindrical end portions is frustum, and frustum root is in cylinder 12 port or flushes with cylinder 12 port. Strengthening cylinder root intensity, improve enabling capabilities, it is to avoid overload global failure, after partial compression deformation in top causes permanent deformation, lower half can carry out appropriateness compensation automatically.
The opening of two cylinders 12, the tapered mouth of indent, the tapered boss of another evagination, this bell and this cone boss against time, composition is connected. When cylindrical end portions lost efficacy, cylinder compresses further, the opening making two cylinders 12 close to each other until fully in contact with, now, bell coordinates with this cone boss, make two cylinders 12 form axial connection, and make two cylinders keep coaxial state, and by base portion, the external force from pedestal is delivered on backing plate, the effective way of raising power transmission, avoiding two cylinders relatively to offset, deflect, thus avoiding damaging the cylinder in cylinder, cylinder, especially avoiding damage to the base portion of cylinder root. Therefore, even if spring failure, cylinder lost efficacy, but the base portion of upper silicagel pad 8 and lower silicagel pad 4 forms support between pedestal and backing plate, still can play damping effect, it is to avoid overall damping effect complete failure.
It is to say, the area of pedestal is big, compared to cylinder, it is less susceptible to lose efficacy. When cylinder lost efficacy, carrying out power transmission by cylinder, the base portion of upper silicagel pad and lower silicagel pad still provides three protective effects.
All the other are with embodiment 1.
In sum, present invention have the advantage that 1), adopt silica gel lid, silicagel pad, silica gel pad, wear-resisting, high temperature resistant, pressure, long service life, is 10 times of General Purpose Rubber pad. 2), the central shaft (i.e. pedestal) of device adopt silicagel pad to position, when spring failure, the cylinder that silicagel pad (includes silicagel pad 8, lower silicagel pad 4) leans, and forms second protection effect. 3), silica gel pad, lower silicagel pad, silica gel ring, upper silicagel pad, silica gel lid adopt silica gel material, reduce noise, reach noise elimination effect. 4), middle employing rigidity spring plays cushioning effect. 5), in product, superstructure all adopts aluminum alloy drawing material, plays demagnetizing action. 6), sheathed cylinder on the cylinder of silicagel pad (including upper silicagel pad 8, lower silicagel pad 4). When the cylinder of spring, silicagel pad all lost efficacy, being transmitted by the power of cylinder, the base portion of silicagel pad can independently form three protective effects.
Technical scheme is applicable not only to the vibration damping of transformator, is equally applicable to similar use environment. Such as water pump, blower fan, handpiece Water Chilling Units, the new blower fan of console model, combined type air conditioner, floor air conditioner, roof type air-conditioner, centrifugal blower etc.
